摘要通过 17个碳纤维布 (以下简称CFRP ,即CarbonFiberReinforcedPolymer)约束混凝土短试件在一次加载情况下的实验研究 ,考察含FRP率和荷载偏心率对FRP约束混凝土压弯构件强度承载力的影响规律。在以往对CFRP约束混凝土压弯构件力学性能理论分析结果的基础上 ,推导了CFRP约束混凝土压弯构件承载力相关方程 ,计算公式形式简单 ,概念明确 ,便于实际应用。简化公式计算结果与理论分析结果和实验结果均吻合较好。 members of beam-column with CFRP(carbon fiber reinforced polymer)restrained concrete were tested under once loading condition.Infulence of CFRP content and loading eccentricity on bearing capacity of those members was observed.The correlation equation of bearing capacity of beam-column with CFRP restrained concrete was deducted based on prevenient theoretical analyzing results on mechanical properties of that.The concept of presented equation is clear,modality is simple and convenient for use.Calculating results by presented equation tallies well with results from theoretical analysis and testing.
